Polytetrafluoroethylene (PTFE) ndi polytetrafluoroethylene (PTFE) ndi polima wolemera kwambiri wa mamolekyulu, chimodzi mwazinthu zosunthika kwambiri zamapulasitiki zomwe zimadziwika komanso zothandiza pamitundu yambiri yazogulitsa zomwe sizinaphatikizidwe kuzinthu zina.
Polytetrafluoroethylene (PTFE mwachidule) ndi mphira wocheperako womwe wakhala ukugwiritsidwa ntchito ngati zosindikizira pazinthu zosiyanasiyana kuphatikiza mpweya, madzi, ndi mankhwala.
PTFE O-Ring Kutentha Kusiyanasiyana
Ngakhale PTFE ali m'munsi mawotchi katundu poyerekeza mapulasitiki ena, zakuthupi kukana mankhwala tandem ndi mphamvu yake kupirira osiyanasiyana kutentha osiyanasiyana (-100oF kuti +400oF) kulola PTFE o-mphete kupereka yogwira kukana nyengo komanso magetsi ndi matenthedwe. kutsekereza.
Chifukwa PTFE ndi zinthu zowuma kwambiri, sizingasungunuke "zosungunuka" - ziyenera kupanikizidwa ndi kusungunula kuti zikhale zothandiza (monga mphete za o).
